Group Competitors by Quadrant

You are given a list of competitors, each with a competitiveness score and an engagement score (both are real numbers). Your task is to group the competitors into four quadrants based on the following criteria:

• Strong Competitor: $x \ge 0.5$ and $y \ge 0.5$
• Promotion Needed: $x < 0.5$ and $y \ge 0.5$
• Re-evaluate: $x < 0.5$ and $y < 0.5$
• Needs Improvement: $x \ge 0.5$ and $y < 0.5$

Here, $x$ represents the competitiveness score and $y$ represents the engagement score. Read the input from standard input and print the output as a JSON dictionary on standard output.

inputFormat

The first line contains an integer n indicating the number of competitors. Each of the following n lines contains the details for one competitor with three values separated by commas:

1. Competitor name (a string; may contain spaces)
2. Competitiveness score (a floating-point number)
3. Engagement score (a floating-point number)

For example:

8
MyFitnessPal,0.8,0.6
Fitbit,0.6,0.8
Google Fit,0.4,0.5
Nike Training Club,0.5,0.7
Strava,0.7,0.7
JEFIT,0.6,0.4
Strong,0.7,0.5
Some App,0.3,0.3

outputFormat

The output should be a JSON dictionary with exactly four keys: Strong Competitor, Promotion Needed, Re-evaluate, and Needs Improvement. Each key corresponds to a list of competitor names that fall into that category, preserving the input order.

Example output:

{
  "Strong Competitor": ["MyFitnessPal", "Fitbit", "Nike Training Club", "Strava", "Strong"],
  "Promotion Needed": ["Google Fit"],
  "Re-evaluate": ["Some App"],
  "Needs Improvement": ["JEFIT"]
}

Some App,0.3,0.3
